SPECIFICATION forming part of Letters Patent No. 600,560, dated March 15, 1898. Application filed July 1 1, 1897- Serial No. 644,505. (No model.)

To all whom it may concern:

Be it known that we, ERNST F. SODERQ UIsr and FRANK A. MCADAMS, citizens of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Antirefillable Bottles,of which the following is a specification.

This invention relates to antirefillable bottles, the object being to provide a simple and inexpensive device of this character so constructed as to prevent refilling after the original contents have been poured therefrom.

Our improved bottle embodies, essentially, a valve-seat in the neck, a guard fitted in said neck and having at its inner end a concave recess, a valve, and a valve-actuator situated between the valve and said recess.

In the form of the invention represented the guard consists of two sections, one set within the other, one member of the guard having a lug or projection fitting in a corresponding notch in the neck of the bottle, and a spreader is preferably furnished to force said lug or projection into the notch when the guard is inserted in place into the neck after the bottle is filled.

In the drawings accompanying and forming part of this specification, Figure 1 is a longitudinal central sectional view of the upper part of our improved bottle. Fig. 2 is a similar View of the neck, showing the position taken by the valve and its actuator when the bottle is tilted to pour therefrom. Fig. 3 is a similar view showing the neck in a substantially horizontal position and the valve as closed. Figs. 4 and 5 are transverse sectional views taken, respectively, in the lines 4 4 and 5 5, Fig. 1; and Figs. 6 and 7 are detail views, in side elevation, of the two sections of the valve-guard.

Similar characters designate like parts in all the figures of the drawings.

In Fig. l of the accompanying drawings a portion of a bottle of ordinary construction is shown, the valve being preferably situated in the neck thereof. The body is designated by B, and the neck by N. The valve may be of any suitable type adapted to close the port 2 in the neck. The valve in the present case is designated by V, and it consists of a sphere or ball of suitable material, such as rubber or glass, resting on the seat 3, and when the bottle is in a vertical or substantially horizontal position,as shown,respectively,in Figs. 1 and 3, the valve is adapted to cover the port 2. When the bottle is tilted to pour therefrom, as indicated in Fig. 2, the valve will roll away from or uncover the port 2, so as to permit the liquid to pass through said port and the neck of the bottle. The wall of the valve-chamber 4 is fluted or grooved, as at 5, so that when the valve is moved away from its seat, as indicated in Fig. 4, the liquid can freely flow under the valve through the grooves 5.

In connection with the valve V an actuator, such as A, is provided, adapted positively to force said valve against its seat 3 to cover the port 2 when the bottle is returned to an upright position after any part of the contents have been emptied therefrom.

The actuator A is a self-operative or gravity actuator, it consisting in the present instance of a sphere or ball heavier than the valve, and it is efiective when the bottle is in certain positions to move the valve against its seat for covering the port 2, whereby the fraudulent refilling of the bottle can be prevented.

In conjunction with the valve and its actuator a guard or plug, such as G, is provided, having a concavity or conical recess 6 at its inner end.

The concavity or conical recess 6 at the inner end of the guard or plug G forms a pocket to receive the actuator'or ball A when the bottle is tilted, whereby the valve V can move away from its seat a sufficient distance to uncover the port 2, as indicated in Fig. 2.

The plug or guard G, which is tightly locked within the neck N, consists of two sections 7 and 8, the smaller section 8 loosely fitting Within the socket 7 in the larger section 7, as represented in Figs. 1, 2, and 3. The inner end of the plug has a series of longitudinal grooves or channels 9, which communicate with the transverse or annular channel or groove 10, formed in the plug-sections 7 and 8, respectively, as shown in Fig. 1. A second series of longitudinal grooves 12 is formed in the two plug-sections, and said grooves also and from thence along the-channels 9, 10, and i 12, and then will pass through the ports 14 into a suitable receptacle. The outer end of the guard or plug G is furnished with an annular flange 15, fitting against the shoulder 16 on the inside of the neck N of the bottle,

ing forced too far into said neck.

' said shoulder preventing theguard from be- One of the sections of the plug or guard, as

the part 8 thereof, is furnished with a looking lug or projection, as 17, adapted to enter a corresponding recess 18 in the-neck of the bottle, a suitable spreader being preferably l furnished to force the lug into the recess to hold the plug in place.

The spreader for theplug is designated by S,and it consists of a rubber or oth-erspring whose opposite ends are inserted into the sockets 19 and 20, formed in the respective plug-sections.

'The bottle having been filled to the proper height, the valve is inserted into the neck N, after which the valve-actuator A is placed in the neck. The two parts of the plug having 5 been assembled .and'the spreader S being in I place, the plug is-inserted in the neck until the flange 15-abuts against the shoulder 16, i

at which'time the locking-lug 17 will have i reached a point opposite'the recess or notch I 18, into which it is then forced by the spreader S.

Means are 'providedto prevent access to the spreader S from the outside, the means in 5 the present case consisting of "the tongue 01v rib 21 on the plug-section 7 ,fitting within the groove or.-n-otch22 in the plu'g sec'tio-n 8, as I shown in Figs. 1, 2, and 3, the tongue or rib 21 being of a length slightly exceeding the 3 width or diameter of the spreader S, so that if a knife or other instrument be introduced into the space between the twoplugsections it will strike the tongue or rib 21, which thereby prevents its entrance tothespreader, so that the latter cannot be severed or removed.

InFig. 1 the bottle is shown in its upright position and the valve V .h-eldagainst its seat 3 and over the port 2 by the gravity-actuator A, so that it is impossible to pour any liquid into the bottle. When the bottle istiltedor inverted to pour; the actuator A will drop into the concavity 6 of the plug, so thatthe valve V can be moved away from its seat by the pressure of the outflowing liquid to uncover the port 2, wherebythe contents or any part thereof can be poured from the bottle.

tially a horizontal line, the spherical actuator-A will be caused to roll along the oblique or inclined face of the concavity 6, thereby acting against the valve to close same, so that "the bottle cannot be refilled when it is in a horizontal or substantially level position.

Having described our invention, we claim 1. A bottle of the class specified comprehending. a neck having a valve-seat; a valve; aplug having a recess in its inner end and constructed in two sections one of which is smaller than the other, the smaller section being loosely fitted in a socket in the larger section and having a locking-lugadapted to enter a corresponding notch in the neck of the bottle, andthe largersection being provided with a tongue located toent-er a groove in the smaller section; a spreader for the plug-section;'and an actuator located in the space between said recess and valve.

2. A bottle of the class specified comprehending a neck having a valve-seat and furnished with an annular shoulder; a valve; an exteri-orly-grooved two-part plug having a recess at its inner end and provided with a flange at its opposite end fitting against said annular shoulder, one of the plug-sections having a locking-lug adapted to enter a corresponding notch in the neck of the bottle, and one of them being provided with a tongue for enteringa groove on the other section; a spreader seated in sockets formed in the two plug-sections; anda gravitative actuator located in the space between said recess and the valve.

3. A bottle of the class specified comprehending a neck having a valve-seat and furnished with an annular shoulder near its outer end; a'valve; a plug constructed in two parts one of which is smaller than, and is loosely fitted in a socket in, the other, one of the sections of the plug havinga locking-lug adapted to enter a notch in the neck, the plug being externally grooved, and the larger 1 section having a tongue adapted to enter a groove inthe smaller sectionand also having a flange fitted against-said shoulder; an -elastic spreader supported in sockets formed in the respective sections of the plug; and a spherical gravitative actuator disposed in the spacebetw-een said recess and the valve.
